When I navigate to a .js file, a popup will appear that says

Warning: You've navigated to a User Script but Greasemonkey is diabled.

It presents the options: Enable, Enable and Install, and Install - none of which seem to do anything.

I should note that Greasemonkey is enabled and I have no trouble installing scripts from

At first I thought this was a conflict with NoScript, but after disabling it, the error persists.

Build info:

  • Build identifier: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0
  • GReasemonkey 1.12

  1. Can you clarify exactly what you mean by "navigate to a .js file"? Have an example URL?

  2. When you do so, do any new details appear in the Browser Console?

Image with warning:

It was happening with me too, but is gone when I disabled a proxy in firefox network panel

The most important thing is any errors that might be logged. If you can put the proxy back and this still happens, it would be really helpful to see the output there. Ideally open it, hit clear, then click the link that gives this error, and copy/paste anything that shows up at that time.

I've seen this happen as well, but when you press the "Show Script Source" button on the install window or "View Userscript Source" from a link's context menu.

Click above link to display install menu.
Click "Show Script Source"
Shows source, but says GM is disabled.

Doesn't seem to install from the locally displayed script source either.

Mozilla/5.0 (Windows NT 5.1; rv:25.0) Gecko/20100101 Firefox/25.0 with GMv1.12

I'll check error log shortly, but there is steps to reproduce.
